Professional mold flow analysis, from the actual situation of the part, Validate potential problem after the part and mold design; Check the fill balance pattern, weld line, air traps, and predict the needed clamp force and injection pressure, warpage, and the runner system is simulated as the mold design.There are material data, part details and tool description, process setup, wall thickness of part, fill time, pressure at the V/P switchover, injection pressure, clamp force, weld lines, air traps, time to freeze, volumetric shrinkage at ejection and deflection etc., According to these parameters we can better improve and targeted modification, in order to save cost, save time, manufacturing a good part high efficiently.
